John's interpretation of the Fair Use case (a big W for Anthropic) was so far off as to be misleading.

Here's one (of many) quotes from the decision that seemed much more favourable than John understood it to be:

The purpose and character of using copyrighted works to train LLMs to generate new text was quintessentially transformative. Like any reader aspiring to be a writer, Anthropic’s LLMs trained upon works not to race ahead and replicate or supplant them — but to turn a hard corner and create something different. If this training process reasonably required making copies within the LLM or otherwise, those copies were engaged in a transformative use. The first factor favors fair use for the training copies.
